Subject: [PATCH] media: mt9p031: Drop bogus v4l2_subdev_get_try_crop() call from mt9p031_init_cfg()
Date: Sun, 20 Nov 2022 15:13:04 +0100	[thread overview]
Message-ID: <20221120141304.80832-1-marex@denx.de> (raw)

The mt9p031_init_cfg() already calls __mt9p031_get_pad_crop(), which
correctly calls v4l2_subdev_get_try_crop() on V4L2_SUBDEV_FORMAT_TRY
or returns &mt9p031->crop on V4L2_SUBDEV_FORMAT_ACTIVE. No need to
call v4l2_subdev_get_try_crop() in mt9p031_init_cfg() again in case
of both V4L2_SUBDEV_FORMAT_TRY and V4L2_SUBDEV_FORMAT_ACTIVE.

This also fixes a splat generated by this call since commit
2ba3e38517f5a ("media: v4l: subdev: Fail graciously when getting try data for NULL state")
because v4l2_subdev_get_try_crop() is called with sd_state = NULL
in mt9p031_init_cfg().

Fixes: 69681cd041648 ("media: mt9p031: Move open subdev op init code into init_cfg")
